Application'filed October 16, 1903.

- Be it known that I, EDWARD Y. LE Fnvnn, 'a i citizen ofthe UnitedStates, residing at Fallsburg, in the county of Sullivan and State ofNew York, have invented certain new and useful Improvements in Apparatusfor Making Cloth-Lined Paper; and I do hereby declare the following tobe a full, clear, and exact description of the invention,such as willenable others skilled in the art to which it appertains r to make anduse thesame.

single passage of the cloth and paper through sheet.

a paper-drying machine when combined with the improvements as set forthin the following description and the accompanying drawing.

One of the methods heretofore used to make cloth-lined paper consists infirst producing a dry sheet of paper and then putting a wet adhesivecoating, such as starch. on the paper, then running cloth onto the paperthus prepared, and then drying the double sheet on some dryingapparatus. Another method by which cloth-lined paper has been producedconsists in starching a sheet of cloth and drying it as a separateoperation, then bringing it to a paper-mill and running it onto a wetsheet of paper, which is then run through a regular paper-dryingmachine. It is thus seen that in each of the methods heretofore used thedouble sheet of cloth-lined paperis only obtained by one of the partshaving to go through a drying operation previous to the operation bywhich it is joined in the double By the use of my apparatus I am able toaccomplish the desired result in a more economicalmanner, asI producethe cloth-lined paper by a singlepassage of the materials through theregular paper drying machine. The double sheet is producedsimultaneously with that of the sheet of paper. In order to ac- Voirattached to the apparatus and provided Serial No. 177,297.

I is a reel of cloth, and K K D arecarryingrolls for same. N N are the ordinary steamdriers of apaper-drying machine. 0 is the finished sheet of cloth-lined paper.

In the operation of my apparatus the paperpulp in the vat A is formed onthecylinderB and is then picked up by the felt M M, passingovercouchroll C and suction-boxes H H and felt-rolls L L. Between thecouch-r0110 and the cloth-roll D the powdered flour is added to the wetsheet of paper by dropping from the reservoir Gin a continuous stream.In order to provide an even quantity of flour from the reservoir G, itis provided with means, such as a shaker-rod R and cam S, forcontinuously agitating the contents of the same. The cloth on the reel Iis made ,to continuously unwind and to pass over the rolls K K and D,when it then meets the wet sheet of paper with the flour on it, andafter passing over the rolls L L it is pressed by the press-rolls E Eand E E. It is then carried by the felt over the driers N N N of theregular paper-drying machine, where the double sheet is finished. 7

What I claim as myinvention, and desire to secure by Letters Patent, is

1. The herein-described apparatus for the manufacture of cloth-linedpaper which consists of the combination of a cylinder dryingmachine witha cloth-reel and a reservoir for the supply of an adhesive medium,'saidreservoir being so located as to supply the adhesive medium to the wetsheet of paper between the forward couch-roll and the press of saidcylinder drying-machine.

2. The herein-described apparatus, which consists of the combination ofa cylinder drying-machine with a cloth-reel and a reservoir for thesupply of an adhesive medium, said reservoir being provided with meansfor cobtaining a substantially even supply of said adhesive medium andsaid reservoir being so located as to supply said adhesive medium to thewet sheet of paper between the forward couch-roll and'the press of saidcylinder drying-machine.
